As long as you meet the qualifications, there will be no problem. Most of the time is just explaining the structure of the course you will teach and showing you around the area with the opportunity to ask them questions.
I applied in-person. I interviewed at Centenary University (Hackettstown, NJ) in Aug 2014
Interview
The interview was pretty simple and to the point- the manager wanted to know my prior work experience and certifications. The pool manager was very friendly and willing to work with the college students on his/her schedules. I felt good about the job and it is probably the best job on campus.
